What's on the menu for Ryukyu's minute mammals?

Japan’s Ryukyu Islands, which includes Okinawa, are the exclusive home to two rare mammals, the Amami rabbit and Ryukyu long-furred rat. These animals are hard to observe, but conservationists wish to find out specific details about their diets. So researchers inspected the teeth from deceased specimens to find out what the animals were eating, and at different times. Their findings show the rabbits have consistent diets, whereas the rats’ change with the seasons.
